Background
Common approaches for distributed interpretation are based on logic (e.g., blackboard) or default reasoning (e.g., DATMS and DTMS).
- Logic-based approaches do not have coherent mechanism to deal with uncertain knowledge.
- Default reasoning treats uncertain knowledge as “believed until there is reason to believe otherwise” and not as “believed to a certain degree”.
- However, decisions often involve tradeoffs and comparison of strength of belief on states of world or outcomes of actions is thus necessary.
